Super Mario RPG import issues

Sorry, 137 was a typo, it's 127 according to d4s who's the authority on SNES carts. Pull it up and tie it to VCC which is any 5V spot. To find the right pin, find a pin which is numbered and count down to 127 counterclockwise.

 

I'm pretty sure I put it to +5V.

By the way, be VERY careful doing this mod, and don't even attempt it unless you are confident about your micro-soldering ability or you will likely screw it up.

We are talking about heating and lifting a VERY fine (and quite delicate) pin in a compact group of pins.

 

btw, sa1 games DO NOT run on consoles that have the cic-chip inside the snes disabled.

that means a sa1 cart wont run on a modded snes, no matter if its set to pal or ntsc mode.
the proper solution here is to install a seperate switch for the snes' cic, of course.

heres a picture of a sa1 cart to avoid any confusion:

That's what I said originally. I was just commenting that your solution would seem the simpler and easier choice for anyone just looking to play their cart.

 

My god, that would have to be some ninja soldering. I don't think I'm up to it, maybe somebody in the electronics labs here in uni might be, I'm sure they've got some decent equipment.

So if I've understood everything so far:
1/ mod the SNES to have a 50/60hz switch, and switch it to 60
2/ mod the cart, connecting pin 127 on the Nintendo SA1 chip to 5v line (which one is this on the cart?), or I can just cut it and leave it.

And then it works? Sorry for hassling but I want to know I'm at least doing the right thing before I fuck everything up ^_^

 

yep, thats it.
60hz mod is optional.
it will still run on an entirely unmodified snes, just a bit slower than on ntsc consoles.
i'd recommend to do the 50/60hz mod while youre at it, though
